Patotsav (Patt Utsav) is the day when ShriThakurji had blessed us to accept seva from us. So in vaarta prasangs many places it comes ShriThakurji ku Panchamrit Kari ke Paath Baithayo.. So that day is Paat Utsav. And Dwij Pat Utsav is the day When Shrinathji bava did padhramani at shrigusaiji's house._________________Jai Jai ShriGokulesh Parivaar,

Vrajbhaktas plays Hori with Shree Prabhu from Vasant to Dolotsav. During this, Vrajbhaktas forgets that Shree Prabhu is king of Vraj i.e Nand Raaj kumar and plays with equality. After 40 days of this play, Shree Prabhu again sits on the 'Paat' i.e. throne of Nandraaj Kumar and thus again the bhav of Swami and Sevak becomes important and main. This is the main bhav of Dwitiya Patotsav. This is the main utsav of Shree Chandravaliji.

Thank you all for the satsang, and thank you Unnatiji I was looking for the answer you provided. Anyway, Vasantbhai Dweej Patt Utsava and Dweitya Patt Utsava are the same Utava.

Normal description of Patt Utsava is as followings:

When Shree Thakorji is first time invited to reside in Nij Mandir, He is invited with Vedic rituals and after the performation of rituals, Thakorji is then invited to sit (Biraje che) on Sinhasan (Thorn). This is the day which is celebrated as Patt Utsava.

The Dwitya (Dweej) Patt Utsava is the Utsava described by Unnatiji. There is also a third Patt Utsava which is celebrated in Nandalaya and this was celebrated on Thakorji's coming of age.

Thank you all for taking part in this short question and answer satsang._________________Dasa nu das
